Abstract: By surveying sediment deposition, it can be necessary to estimate distribution of several fine and coarse sediment fractions. Subdivision of sediments into the necessary fraction number is used in this case. However, the usual multifraction methods allow only a limited number of fractions. When the sediment fractions are of very different size and concentrations, these methods can be not always sufficiently accurate. The existing multifraction models have limited possibilities because of assumption that no interaction between the fractions occurs[1, 2]. It is sufficiently real only for predominating fractions, when their concentration is enough higher than the transportable one. Therefore it was necessary the supplements of the calculation methods.
